Chapter in this post:
If you have several tabs open in a current version of the Apple web browser Safari on the Mac, the respective website is displayed as a small preview when you hover over a tab with the mouse cursor. Maybe this annoys you or you fear that it will lose valuable computing power. Or you just don't want to be distracted by other sides just because you move the mouse. Whatever the reason, there is not just one solution, but two solutions to the problem. How you can deactivate the tab preview in Safari, you can read that in this guide;)
So far, Apple has not implemented a simple solution for users in Safari or the macOS settings with which the tab preview in the web browser can be switched off. That's why the route here once again leads through the terminal. But don't worry, only one command line is required for both possible solutions. But before that there is a little detour into the security settings.
There are a few hidden menus for the Safari menu bar, such as "Developer", From which I sometimes use the" clear cache memory "function to solve local problems with websites. However, the Debug menu is another one that hides a little better. And this is how you can activate it:
defaults write com.apple.Safari IncludeInternalDebugMenu 1
If you click on the debug menu you will probably see many menu items in English. But that doesn't matter. You only need "Tab Features", which is at the bottom of the list. Move the mouse cursor over it and remove "Show Tab Preview on Hover (requires restart)" from the selection that opens. As the menu item suggests, Safari must be restarted for the change to take effect.
If you don't want to activate an additional menu after getting rid of the tab preview in Safari on the Mac, you can also switch off the display of the website content when hovering over the browser tabs directly in the terminal. However, the above guide is the easiest way to quickly reactivate the tab preview if you want it back or if you share your Mac account with someone who liked it. If this is not the case, you proceed as follows:
defaults write com.apple.Safari DebugDisableTabHoverPreview 1
You can reactivate the Safari tab preview by entering the line shown under point 9 again, but using a 1 instead of 0 at the end. The same applies to removing the debug menu: use point 9 of the first list and replace the 1 with a 0. Good luck with adapting the Safari browser on your Mac;)
